Sounds good: Hi. Yes, that is good for you to be taking; your level was too low. It's also good to take it with food (preferably food that contains some fat) to augment it's intestinal absorption. AM versus PM doesn't matter. You should also get enough calcium.

Consider higher dose: Most adults need 5000-8000 iu/day to achieve optimal blood levels of 50-80- given your weight you will probably need about 5000/day. But with levels so low I advise 10,000 iu/day for a month to get your levels up more quickly.

I would suggest a: higher dose, such as 50,000 u of d3/week for several months before rechecking levels. 2000-4000/day is appropriate for maintenance once your levels are normal. Also, the capsules are much cheaper than the liquid. Take any time of day, with or without meals.
